Section 3.8.3 Macro Replacement
Semantics, paragraph 2:

   If a # preprocessing token, followed by an identifier, occurs lexically at
the point at which a preprocessing directive could begin, the identifier is
not subject to macro replacement.

This is from the December 7, 1988 draft.  Looks like it's illegal.
